After a quick Google Patents search (thanks Mord) I'm going to stay quiet. There has been some various patents in this area but I think my modifications are pretty distinct. I am going to ponder this for a bit and might actually consult a patent attorney to see if my ideas warrant a patent.

I was offering to assist in the search, but if you have a little money for it Consult an attorney. They may recommend doing a little preliminary work and ordering some drawings in order to file a provisional application whIle you determine tge claims and research prior art.

Thanks for the tip. You can patent a type of device though? This is an idea to make a very new and different type of an existing device. I am sure the existing device is not patented.
If I'm reading you correctly you're offering to access Google Patents for me?

If your device is simply taking an existing device and rounding the corners on the device, I regret to inform you that Apple already owns the patent on that.
